Constant vomiting and Diarrhea

[Sarah407]

Hi,I'm 17 years old and during the past month every few days or week I'd feel nauseous and start vomiting and get diarrhea for a whole day and I wouldn't eat until the next day. And after a few days the same thing would happen.
So can anyone tell me what's wrong? is it something serious??

If it appears again, consider it as some food intolerance. Or allergy.

[Sarah407]

Actually it just stopped for the past few days without taking any medication...is that normal?

[boron]

There is fructose in processed meat and in sweetened milk. Sorbitol, xylitol or HFCS are often used as sweeteners. In fructose intolerance you should avoid them all.

You can have two diet trials by yourself:

1. Exclude all dairy for 2 days. If you are lactose intolerant, symptoms should go away in this time.
2. Exclude anything containing fructose for 3-4 days (fruits and any fruit product, anything with High Fructose Corn Syrup, also anything with sorbitol (diet colas, sugar fre chewing gum, low calorie foods), honey. If you're fructose intolerant, symptoms should lessen in this time.

Both fructose and lactose intolerance go with bloating...

It first started at the first of July after I ate pasteries for breakfast and at noon I felt nauseous and had diarrhea for the rest of the day and after a week or so I ate big mac and it going on from since. Once I drank chocolate milk for breakfast and then I started to vomit and had diarrhea and another time I woke up and started to vomit like two times and had diarrhea three times without eating it's like my stomach is storing the food and then getting rid of it at once..the stool liquid but I'm not sure about the color..is this information good enough?

[boron]

Vomiting and diarrhea, you mentioned, made me think, it's an infection...and parasites are known to cause this prolonged vanning/waxing diarrhea.

To say more I'd need more history from you. How are symptoms related to meals, to which food, what's the color of the stool, any mucus, any other health problems, what happened a month ago...?  It may even be an inflammation (Crohn's disese or celiac disease)...anything like this occurs in your relatives?

It could be intolerance to lactose (dairy) or fructose (fruits), but vomiting is not typical here.

I've seen a doctor and all the lab results were fine and I just did the stool test and I'm waiting for the results.Do you have any idea what it might be?

[boron]

It's serious enough to see a doctor.

First, I think you need a stool test for parasites.
